Universal HEAD DEMAGNETIZER for Cassette Tape Deck Recorder Reel to Reel 8 Track VHS Audio Video

I have purchased this product to de-magnetize the cassette recorders playback heads of my collection. I brought it from USA through my friend and I found that there is no specifications on power supply voltage on the package. (110 V or 220V ). So, till date i have not used it. Even in so many web pages it was not mentioned about operating voltage of this product. Now it is in my collection as a display piece. If any one knows about its operating voltages (In INDIA 220V to 230V AC power supply) please post your reply here in reviews, It will help me a lot. Thanks in advance...

It's to be used with 110V, don't use with 230V it will blow up.
